10.6.    Payment of Expenses; Summary Statements. Subject to reconciliation and the limitations provided in Section 10.7, the Party initially incurring Program Expenses will be responsible for and pay for all such Program Expenses so incurred. Each Party will maintain the books and records referred to in Section 10.8. Each Party will report all Program Expenses, Sublicense Revenue and Net Sales in accordance with the terms and conditions hereof and in accordance with GAAP. If any Program Expenses relate to multiple Shared Products, the Parties will work together to determine an equitable allocation of such Program Expenses between such Shared Products. Within [***] Business Days after the end of each Calendar Quarter, each Party will submit to the other a written report reflecting, on a Shared Product-by-Shared Product basis, the estimated Program Expenses, Sublicense Revenue and Net Sales during the just-ended Calendar Quarter, except that each Party’s submission for the last month of such Calendar Quarter will be a good faith estimate and not actual amounts (each, a “Summary Statement”). Within [***] days after the end of each Calendar Quarter, each Party will submit to the other an updated Summary Statement reflecting, on a Shared Product-by-Shared Product basis, the actual Program Expenses, Sublicense Revenue and Net Sales for the last month of such Calendar Quarter, which Summary Statement will be certified as true and accurate by a representative of such Party that is a Vice President of Finance or more senior representative. Each Summary Statement (after the initial Summary Statement) will reflect an adjustment for the actual amount of the previous Calendar Quarter as needed, provided that, if, prior to preparation of a Summary Statement in accordance with the preceding sentence, a Party discovers that actual Program

Expenses, Sublicense Revenue or Net Sales with respect to a Shared Product have deviated materially from any non-binding, good faith estimate of such Program Expenses, Sublicense Revenue or Net Sales submitted to the other Party in accordance with this Section 10.6 (including any deviation in any single Expense or in aggregate Sublicense Revenue or aggregate Net Sales, in each case, of more than $[***]), then such Party shall promptly notify the other Party of such deviation in advance of delivery of such Summary Statement. Any reporting and reconciliation of variances between estimated and actual Expenses may be delayed by a Calendar Quarter as reasonably necessary in light of a Party’s internal reporting procedures. The Parties’ respective Summary Statements will serve as the basis of the Reconciliation Reports prepared by [***] pursuant to Section 10.7. The Parties’ respective finance departments, coordinated by the Alliance Managers, will meet at least [***] per [***], or as otherwise mutually agreed by the Parties, to discuss any questions or issues arising from the Summary Statements, including the basis for the recognition of specific Program Expenses, review cost estimates and forecasts, and discuss reconciliation and reporting procedures.

10.7.    Reconciliation.

10.7.1.    General Reconciliation. [***] will prepare a reconciliation report, as soon as practicable, after the receipt of [***] updated Summary Statements, but in any event within [***] days after the end of each Calendar Quarter, accompanied by reasonable supporting documents and calculations sufficient to support each Party’s financial reporting obligations, independent auditor requirements and obligations under the Sarbanes-Oxley Act, which reconciles the amounts accrued and reported in each Party’s Summary Statements and the share of the Net Profits and Net Losses to be allocated to each of the Parties for such Calendar Year in accordance with Section 10.4, on a Shared Product-by-Shared Product basis and in the aggregate across all Shared Products (such report, the “Reconciliation Report”).

10.7.2.    Excess OPEX Deferral. Schedule G sets forth the limits on CRISPR’s share of the Program Expenses for the Initial Shared Product for each of Calendar Years 2021, 2022, 2023 and 2024 (such limit for the applicable Calendar Year, each an “Annual OPEX Cap”). To the extent that the Reconciliation Report for Calendar Years 2021, 2022, 2023 or 2024 indicates that CRISPR’s share of the Program Expenses for the Initial Shared Product for such Calendar Year exceeds [***]% of the Annual OPEX Cap for such Calendar Year, CRISPR shall be permitted to defer payment of an amount equal to such excess amount (the “OPEX Overage”) as set forth in Section 10.7.3.

10.7.3.    Payment. Subject to the limitations provided in this Section 10.7, payment to reconcile aggregate Net Profit or Net Loss, as applicable, across all Shared Products shall be made by the owing Party to the other Party within [***] days after such Reconciliation Report is complete; provided that, CRISPR shall be permitted, by written notice to Vertex within such [***]-day period, to defer payment of any OPEX Overage, and such OPEX Overage shall not be currently charged to or payable by CRISPR during or in respect of such Calendar Year and instead will be deducted from Net Profits payable thereafter to CRISPR for the Initial Shared Product, provided that, the maximum deduction against such Net Profits for any single Calendar Year for any and all deferred OPEX Overages shall be limited to [***] and, provided, further, that any portion of an OPEX Overage which is not deducted from such Net Profits by application of such cap shall be carried forward for deduction against future distributions of such Net Profits until such OPEX Overage amounts have been deducted in full. For the avoidance of doubt, the deductions contemplated by this Section 10.7.3 may only occur in a Calendar Year in which there is a Net Profit payable to CRISPR with respect to the Initial Shared Product.

10.8.    Books and Records. Each Party will keep and maintain accurate and complete records regarding Program Expenses, Sublicense Revenue and Net Sales, as applicable, during the three preceding Calendar Years. Upon [***] days’ prior written notice from the Auditing Party, the Audited Party will permit an independent certified public accounting firm of internationally recognized standing, selected by the Auditing Party and reasonably acceptable to the Audited Party, to examine the relevant books and records of the Audited Party and its Affiliates, as may be reasonably necessary to verify the Summary Statements and Reconciliation Reports. An examination by the Auditing Party under this Section 10.8 will occur not more than once in any Calendar Year and will be limited to the pertinent books and records for any Calendar Year ending not more than [***] months before the date of the request. The accounting firm will be provided access to such books and records at the Audited Party’s facility or facilities where such books and records are normally kept and such examination will be conducted during the Audited Party’s normal business hours. The Audited Party may require the accounting firm to sign a customary non-disclosure agreement before providing the accounting firm access to its facilities or records. Upon completion of the audit, the accounting firm will provide both the Auditing Party and the Audited Party a written report disclosing whether the applicable Summary Statements and Reconciliation Reports are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to the Auditing Party. If the report or information submitted by the Audited Party results in an underpayment or overpayment, the Party owing underpaid or overpaid amount will promptly pay such amount to the other Party, and if, as a result of such inaccurate report or information, such amount is more

than five percent of the amount that was owed, the Audited Party will reimburse the Auditing Party for the reasonable expense incurred by the Auditing Party in connection with the audit.

10.9.    Payment Method; Currency.

10.9.1.    All payments under this Agreement after the Amendment Effective Date will be paid in U.S. Dollars, by wire transfer (a) in the case of payments to [***], by [***] to an account of [***] designated by [***] (which account [***] may update from time to time in writing) and (b) in the case of payments to [***], by [***] to an account of [***] designated by [***] (which account [***] may update from time to time in writing).

10.9.2.    If any amounts that are relevant to the determination of amounts to be paid under this Agreement or any calculations to be performed under this Agreement are denoted in a currency other than U.S. Dollars, then such amounts will be converted to their U.S. Dollar equivalent using the [***] of the official rate of exchange of such domestic currency as quoted by [***], for the Calendar Quarter for which the payment is made.

10.10.    Late Payment. Any undisputed payments or portions thereof due hereunder that are not paid when due will accrue interest from the due date until paid at an annual rate equal to [***] plus [***] percent (or the maximum allowed by Applicable Law, if less).

(c)    Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in this Section 17.2.3 disputes in good faith the existence, materiality, or failure to cure of any such breach that is not a payment breach, and provides notice to the Non-Breaching Party of such dispute within the relevant cure period, the Non-Breaching Party will not have the right to terminate this Agreement in accordance with this Section 17.2.3, unless and until the relevant dispute has been resolved. It is understood and acknowledged that during the pendency of such dispute, all the terms and conditions of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder.

17.2.4.    Termination for Patent Challenge. If a Party (the “Challenging Party”) (a) commences or actively and voluntarily participates in any action or proceeding (including any Patent opposition or re-examination proceeding), or otherwise asserts any claim, challenging or denying the validity or enforceability of any claim of any Patent that is licensed to the Challenging Party under this Agreement or (b) actively and voluntarily assists any other Person in bringing or prosecuting any action or proceeding (including any Patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim of any Patent that is licensed to the Challenging Party under this Agreement by the other Party (the “Non-Challenging Party”) (each of (a) and (b), a “Patent Challenge”), then, to the extent permitted by Applicable Law, the Non-Challenging Party shall have the right, in its sole discretion, to give notice to the Challenging Party that the Non-Challenging Party may terminate the license(s) granted under such Patent to the Challenging Party [***] days following such notice, and, unless the Challenging Party withdraws or causes to be withdrawn all such

challenge(s), or in the case of ex-parte proceedings, multi-party proceedings, or other Patent Challenges that the Challenging Party does not have the power to unilaterally withdraw or cause to be withdrawn, the Challenging Party ceases assisting any other party to such Patent Challenge and, to the extent the Challenging Party is a party to such Patent Challenge, it withdraws from such Patent Challenge within such [***]-day period, the Non-Challenging Party shall have the right to deem the Challenging Party to have exercised an Opt-Out with respect to any Shared Product(s) Covered by a Patent that is the subject of such Patent Challenge, by providing written notice thereof to the Challenging Party, in which case the provisions of Section 17.3 shall apply; provided, however, [***]. The foregoing right of the Non-Challenging Party shall not apply with respect to any Patent Challenge where the Patent Challenge is made in defense of an assertion of the relevant Patent that is first brought by the Non-Challenging Party against the Challenging Party. For the avoidance of doubt, any participation by the Challenging Party or its employees in any claim, challenge or proceeding in response to a subpoena or as required under a pre-existing agreement between the Challenging Party’s employee(s) or consultant(s) and their prior employer(s) shall not constitute active and voluntary participation or assistance and shall not give rise to the Non-Challenging Party’s right to deem the Challenging Party as having exercised an Opt-Out with respect to any Shared Product hereunder.

17.2.5.    Termination for Insolvency. If CRISPR (or any CRISPR Entity(ies)) undergoes any Insolvency Event, then Vertex may terminate this Agreement in its entirety effective immediately upon written notice to CRISPR.

meaning of Section 365(n) include laboratory notebooks, cell lines, product samples and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference therein, the Licensed CRISPR Technology and all information related to the Licensed CRISPR Technology. If (x) a case under the U.S. Bankruptcy Code is commenced by or against CRISPR (or any CRISPR Entity(ies)), (y) this Agreement is rejected as provided in the U.S. Bankruptcy Code, and (z) Vertex elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, CRISPR (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(i)    provide to Vertex all such intellectual property (including all embodiments thereof) held by CRISPR and such successors and assigns, or otherwise available to them, immediately upon Vertex’s written request. Whenever CRISPR or any of its successors or assigns provides to Vertex any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 17.2.5(a)(i), Vertex will have the right to perform CRISPR’s obligations hereunder with respect to such intellectual property, but neither such provision nor such performance by Vertex will release CRISPR from liability resulting from rejection of the license or the failure to perform such obligations; and

19.14.    Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing herein contained will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party.
